Supply of Early Streamer Emmission Air Terminal (ESEAT). Model : L .The ESEAT has corrosion resistant stainless chrome body made up of AISI 316 grade of height 0.50 meters capable of working in hazardous atmosphere.The Air terminal is non - radioactive and requires no special licensing. The unit is fully autonomous (no battery, no external power supply is required),collects energy from the ambient electric field. The ESEAT model has been tested in a high voltage laboratory in accordance with NFC 17 102 in order to measure the average gain in triggering.The average gain in triggering time (ΔTs) obtained during the lab test for the offered model is 60 µs.

The ESEAT works on negative as well as positively polarized discharges. ESEAT has been tested for such discharges in Central Power Research Institute (CPRI). A dedicated tester is available to test the healthiness of the ESEAT on request (Page No.37,Point No. 3 of Clause 8.6 of the revised NFC 17-102 version 2011).
